CARRIAGE-BODY.

Specification of Letters Patent No. 29,386, dated July 31, 1860.

To all whom it may concern:

Be it known that I, ERNST KIRSGH, of the city and county of New Haven, in the State of Connecticut, have invented a new and useful Improvement in Carriage- Bodies; and I do hereby declare that the following is a full, clear, and exact description of the construction, character, and operation of the same, reference being had to the accompanying drawings, which make part of this specification, in which Figure l, is a birds-eye view of a section of the body, and seat, showing a portion of the seat rail. Fig. 2, is a plan of one of the sides of the body and a part of the seat rail. Fig. 3, is a perspective view of the skeleton of the body, showing both sides, and the seat rail with the seat attached. Fig. 4, is a direct side View of a carriage, showing the shape of the body, reach, &e.

My improvement consists in making each side of the body, and one half of the seat rail, of a single piece of timber, as split from the log, so that no part shall be cross grained; and, in sawing, or splitting, the rear portion as far forward as is necessary to form one half of the seat rail; and, in then bending the parts into suitable curves, or sweeps, to form the skeleton frame, or body, ready to receive the bottom boards, and seat, when it will be ready to be attached to the spring bars; thus using but two pieces of timber to form the ,whole frame of the body, and making each part of any desired curve or sweep, and yet no part, or portion will be cross grained, thus giving the great est amount of strength with the least weight of wood.

To make each side of the body, and one half of the seat rail, I take one piece of timber as split from the log, and split or saw open the rear portion far enough to form one half of the seat rail; and, after the proper dressing, I bend that portion which is to form the side of the body substantially into the form, or shape, represented at A, Figs. 2, 3, and 4, and that portion whichis to constitute one half of the seat rail, substantially, into the form, or shape, represented at B, Figs. 2, 3, and 4, so that the two sides and the whole of the seat rail, will consist of but two pieces of timber, as repre sented in Fig. 3, while no part will be cross grained, thereby preserving the full strength of the fibers, with the additional support of the curves. I then fit in the bottom boards, (in front of the seat,) in the usual way; and I fit in the seat, C, substantially, as repre sented in Fig. 3 and indicated in Figs. 2, and 4, or in any other convenient way of fitting a light seat, the great object being to combine lightness with, strength, while symmetry and neatness are preserved. I attach the body to the spring bars of the running gear in the usual way, substantially, as represented in Fig. 4. I also make the reach, or perch, of a straight piece of timber, and bend it to the desired shapethat is, suited to the shape of the body, as represented at D, Fig. 4thus giving it much more strength in proportion to the weight of timber than could be obtained by cutting the curves across the grain.

The advantages of my improvement consist, in that, the body can be made at less expense for labor; with much less timber, and much less iron, while it will possess much more strength, and yet be much lighter, which is a characteristic very highly prized by those who use sporting wagons; while the strength, and beauty, will 'commend them to all.

I may make the two sides of the body, and the whole of the seat rail, of one piece of timber of double the lengthand work it from the middle, but in that case the finished body will only differ from the one already described, by not having a lap in the center of the seat rail, as there must be when two pieces are used; but the lap does no harm, and it is more convenient to work the shorter pieces.

I am aware that timber'has been bent for a very great variety of purposes; and that curved sides, and reaches, are very common in carriages. I, therefore, do not claim either of them, as such, as my invention; but,

What I claim as my invention, and desire cut across the grain of the timber, and the to secure by Letters Patent, iswhole is constructed, and fitted for use, sub- 10 The construction of thfi crooked or curved, Stantially, as herein described. body, when no more t an two pieces are 1 5 used to compose the two sides of the body, ERNST KIRSCH' and the seat rail, while the fibers of the tim- Witnesses: ber always run in the direction of the curves, HOMER H.
